HENRY C. IVEEDEN, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO TIIE WEEDENSANITARY MANUFACTURINGCOMPANY, OF RHODE ISLAND.

AUTOMATIC FLUSHING DEVICE FOR URINALS.

SPECIFICATION forming part of Letters Patent No. 416,133, dated November26, 1889.

Application filed March 11,1889. Serial No. 302,777 (No model.)

To all whom it may concern.-

Be it known that I, HENRY O. IVEEDEN, of Boston, in the county ofSuffolk and State of Massachusetts, a citizen of the United States, 5have invented certain new and useful Improvements in Automatic FlushingDevices for Urinals, of which the following is a specification.

My present improvement relates to that class of devices for producing anautomatic flush of the bowl of a urinal or similar structure wheneverthe same is used, in which devices a siphon flushing-pipe extending fromthe supply-tank to the bowl to be flushed, is set in motion by means ofrarefaction of the air in the long leg of the siphon, this rarefactionbeing produced through the instrumentality of an air -pipe extendingdownwardly from a point near the top of the long leg to a point in thedischarge-pipe below the urinal-bowl.

The object of my invention is to improve the construction of thespecific devices whereby the passage out from the urinal-bowl of liquidintroduced therein produces the exhaustion or rarefaction of air in thelong limb of the siphon.

In the accompanying drawing I have repre-' sented in vertical sectionand elevation a-de- Vice embodying my present improvel'nent.

In that drawing, A represents the tank; 13,

the siphon-discharge pipe; O,

the bowl to be flushed; D, the outlet thereof, and E the drawpipe orexhaust-pipe.

chanically confined therein.

The escape or rushing out of this water produces a rarefaction of theair in thelong leg of the siphon,

and thus'starts its flow.

For this purpose I form at a point upon the discharge-pipe of the bowl achamber or enlargement F, into which the fluid introduced into the bowlwill pass.

Into this chamber moreover. I lead a pipe E, and I close its extremitytherein by means of a weighted valve G.

The weight of this valve is to be but slightly inexcess of the column ofwater normally standing in the pipe which it is to balance.

The dischargepipe D continues, as shown, beyond the enlargement F, andwill preferably be trapped therein, as shown. The elevation of the mouth5 5 of this lower portion of the discharge-pipe above the bottom of thechamber will govern the normal level of the waterleft therein after theflushing action.

In order that the introduction of fluid from the bowl into the chamber Fshall cause the valve G to lift, I may provide it with a float, as shownin dotted lines, and when thus constructed the operation of the deviceis as follows: The parts are represented as in their normal condition,the exhaustpipe B being held full of water left by the previous flush,and counterbalanced therein by the weight of the valve G, and water alsostanding in the enlargement or chamber F, as shown. Now, if fluid beintroduced into the bowl it will pass into the chamber F, raising thewaterlevel therein and floating up the valve G. This releases the waterstanding in the drawpipe E, and the sudden downward passage of thiswater rarelies the air in the long leg of the siphon with which the pipeE connects and at once starts the siphon. I may, how ever, dispense withthe float upon the valve by the following modification of the parts: Icarry the pipe from the bowl into the chamber below the normalwater-level therein, and I place in the upper portion of said chamber anoutwardly-openin g air-relief valve f. Now, it the outlet -pipe D hasthe siphon form shown, the introduction of fluid from the bowl into thechamber, raising the water level therein, will start the siphon D,air-compression in the chamber being prevented by the opening of therelief-valve. \Vhen the siphon D starts, the withdrawal thereby of fluidfrom the chamber F, rarefying the air therein, will cause the valve G tolift and permit the water in the pipe E to flow down.

I make no claim herein to any method of operation of the device shown,the same forming the subject of an application filed by me March 15,1880, and serially numbered 303,407.

I claim- 1. In a device for causing the automatic flushing of the bowlof a urinal or similar structure, the combination, with the said bowl,its supply-tank, and siphon flushing-pipe, of a discharge-pipe leadingdownwardly from the bowl, a water-chamber connected therewith, and apipe extending from the long leg of the siphon flushing-pipe down to thesaid water-chamber and having its lower aperture covered by a valveweighted to counterbalance the column of water normally standing in thesaid pipe, all substantially as set forth.

2. In a device for causing the automatic flushing of the bowl of aurinal or similar structure, the combination, with the said bowl, itssupply-tank, and siphon flushing-pipe, of a discharge-pipe leadingdownwardly from the bowl, a water-chamber connected therewith, a pipeextending from the long leg of the siphon flushing-pipe down to the saidwater-chamber and having its lower aperture covered by a valve weightedto counterbalance the column of Water normally standing in the saidpipe, and a float attached to said valve, all substantially as setforth.

In a device of the character described,

' the combination of the following elements: a

outlet-pipe from the bowl to the said cham-.

ber sealed by the water therein, a pipe extending from the long leg ofthe siphon flushingpipe down to the said waterchamber and having itslower aperture covered by a valve weighted to counterbalance the columnof water normally standing in the said pipe, and a siphondischarge-outlet from said waterchamber, all substantially as set forth.

In testimony whereof I have hereunto subscribed my name this 7th day ofMarch, A. D. 1889.

HENRY C. VVEEDEN.
